Comprehensive and Detailed In-Depth Explanation:
In embedded EWM within SAP S/4HANA Cloud, Private Edition, goods receipt (GR) for external procurement can be posted using two primary methods. Option B ("Use the ERP Inbound Delivery to post goods receipt") is correct because the ERP inbound delivery (created in SAP ERP/S/4HANA MM) serves as the reference document, which is then replicated to EWM for warehouse processing. Option C ("Use the EWM Inbound Delivery to post goods receipt") is also correct because the inbound delivery in EWM, derived from the ERP document, is where the actual GR is confirmed and posted back to ERP via integration. Synchronous GR (options A and D) is not a standard feature in embedded EWM for external procurement, as the process relies on asynchronous communication between ERP and EWM via queued remote function calls (qRFC). The GR posting is finalized in ERP based on EWM confirmation, ensuring inventory alignment.
